Because fewer and a faulty auto correct.

Switches and checkboxes that are unclear if they are on or off and which option does what.

I see it a lot in games where it is extremely unclear from the wording and the swith/checkbox if it needs to be on/checked or off to make the thing do as you want.

And when the swith has a light green and slightly grayer light green or similar as ita colours it doesn’t help, because not only doesn’t you know what way the swith need to go to get the outcome you want. You doesn’t know what way the swith is going anyway.
